ASSEMBLING MACHINE.

Application filed September 14, 1917. Serial No. 191,469.

To all whomit may concern.

Be it known that LYVILLIAM C. STEWART, a subject of the King of England,residing at Swampscott, in the county of Essex and State ofMassachusetts, have invented. certain Improvements in Assemblinglviachines of which the following description, in con nection with theaccompanying drawings, is a specification, like reference characters onthe drawings indicating like parts in the several figures.

This invention relates to machines for assembling parts of boots andshoes upon their lasts preparatory to the pulling-over and lastingoperations. For the purpose of illustration, an embodiment of theinvention is herein shown as applied. to a machine 01" the typedescribed in Letters Patent of the Unitei States No. 1,356,510 grantedoctober 26, 1920 on application oi Hannah nshton, executrix of the willof Orr-ell Ashton. l" is to he understood, however, that the inventionis not restricted to embodiment in a machine of the par 'icular typedisclosed in said patent.

In the earlier machine, above referred to, mechanism is provided forinserting tacks into the shoe bottom through the flange of the counteror hcel stiffener and into the heel seat. the tack: mechanisms beingerried to a point leyond the ups-itamliug margin oi. the upper and thetacks inserted through the flange of the counter and the innersolewithout passing through the upper. It is important that these tacks,which may be termed counter-flange tacks, be driven at predetermineddistances from the last edge, .notwithstaudii ariations in widthot thelasts i prei' -a le that they should be so it ated ind dri iautomatically.

important feature of this inventio for insur' not t counter tacos l?alive. predete mined distances from the edge, rres ui ctively of the.widtl'l oi he last.

shown herein, the hinge tackers and shoe 1 seat are at predetermineddistances from the last edge. The tackers are preferably positzoned nearto ether during the r'movement of advance over the heel seat so thatthey will more readily pass beyond the upstanding margin of the upper atthe rear of the shoe and are then separated to their tack drivingpositions. The separation of the tackers is preferably effected bymechanism which is positioned in accordance with a dimension of the shoeand which calipers, for example, the width of the shoe, the caliperingmechanism co-operating with means on the tackers during their movementof advance over the shoe bottom to cause them to separate until they arelocated at predetermined, constant, and preferably equal distances fromthe opposite edges of the last bottom.

In the machine of the prior patent refferred to above the countertackers, after they have advanced over the shoe into tack drivingposition, are out of contact with the work, there being a spacebetweenthe ends of the t acker nozzles and the flange of the counter. Thetacks, therefore, have to be driven through the air. As a conse quencethe points of the counter tacks sometimes shoot sideways and the tacksare therefore not driven straight into the work.

Another feature of the present invention consists in. means for insuringthat the counter tacl f. mechanisms have their tack nozzles or holdersmoved toward the work before the taclcs are driven. As herein shown, thetack holders are mounted For limited movement toward the work, and meansoperated by movement of the tack drivers in the early part of theirdescent is provided to move the tack holders into contact with the workin advance of the action of the drivers to drive the tacks through thetack holders into the work. In the illus trated embodiment of theinvention this movement of the tack holders eflccted yieldingly throughsuitable springs.

in the ma ....no she v'n in the patent above l"- l=. QTi'(l to.mechanism including a fined lower abutment s provided for rigidly :ci:nping the shoe upper against the cone of the, last at a point remotefrom the last hottoin while the margin of the upper estending above thebottom oi? the lastv is seized and tcnsioned over the heel seat as thewiper advances. It is desirable that the lower abutment accommodateitself to different sizes and shapes of lasts so that theywill,

be pro iierly positioned in. the machine for the action of the'gripper,wipers, and other operating mechanism without attention of the operatorand without his taking time to make adjustments.

.-i .n.ot-'her feature of the present invention consists, therefore, inmeans by which the lower abutment is rendered self-adjustii-ig to lastsor? different sizes and shapes, and means by which the abutment,afterthe last has reached a predetermined position in the machine, isrendered unyielding to permit the last to be clamped-in the machine by.rearward'ly directed pressure. As shown herein. the lower a l'niitmentis mounted for movement longitudinally of the shoe. and. the upperabutment is imilarly moimtcal, mechanism being provided. for renderingthe lower ubutment unyielding when the upper abutment is movedreznwvardly or inwardly. Y J

It is important that the margin of the upper at the rearof the heel seatbe properly located between the end of the wiper and the gripper whichco-operates with it to seize the upper margin before the machine isstarted. In the normal operation of the n'n'ichine the shoe is, loweredas it is swung the gripper the shoe is per is positioned. directlyinside the margin of the upper .l11(l against the heel seat or 'flang eofthe counter and carrirnl with the shoe'as the shoe is pushed 'h'irthcrinto the machine.

Another feature of the invention cons in the combination with grippingmeans and operating menns'therefor, of means torrenderi'ng the"operating means inoperative until the gripping means has been closedupon the stock. The gripping means may comprise a wiper and a grippingelement (xi-operating therewitln the mechanism being organized toprevent movement of the gripping element by the operating means unlessthe gripping element is moved toward the wiper and in to proximity tothe wiper in position to do its work. Thismechonism prevents thencechine from hein .tarted until the gripper properly loc ted relativelylo' the u .11 it is to seize and the shoe is on tioned iii the ma.llIlG.

also inrportzint that the wji th of the toxin"; or of the F? up when awhole uuip d, lro'n'i the seam uniting the lore ing and quarter to theheel seat be constant inshoes of a given style. Accordingly, a, featureoi' the invention consists in means for positioning the shoe verticallywith the seam uniting the quarter and foxing at a predetermined distancefrom the plane in which the wiper acts, so that by relative adjustmentof the upper and the last the amount wiped over upon the heel seat mayvaried "to the Width of the foxing fromv the seamto the heel seat constant. 5

'llhese and other features of the invention will appear more fully fromthe followingdetailed description when read in connection with theaccompanying drawings and will be pointed out in the appended claims.

The shoe is placed upon a last pin 8 and swung toward themachine. rar ying the pin 8 is depressible against a light spring notshown. hen the shoe A "post i. l l

rises, after being depressed and moved toward the machine the margin ofthe upper at the rear of the heel seat rises between n gripping elementil'ln'nied as a jaw 26 and i '1he wiper is z-shown in. F. t or teethapted in formations on the a. T-way 32} on a. relatively fixed part 35se cured to the frame. Upon the rear end of the slide 3]. is secured ablock 32 on which is a ratchet plate 34 having rearwardly directedteeth'36: Below the plate 34 is mounted a pairoitpawls 38 on a pin 40which is sup- 7 30 is carried by a. slide 3]. having a T-guide 33engaging aiilvancing wiper so that theportion of the upper at the rearof the shoe which lies above the lower abutment 30 will be tensioned asthe wiper and gripper move over the shoe bottom.

7 The shoe having been positioned as described, the treadlc 86 may bedepressed to start the machine, whereupon a hook 110 co-operates with aroll 112 on the jack member 6, as is fully described in the firstabovementioned prior patent, to draw the shoe in wardly of the machine,lock it from downward movement, and clamp the portion of the shoeadjacent to the edge of the counter which is most remote from the soleagainst the abutment 30 which has been locked against further movementin response to pressure of the shoe against the upper abutment 54 asdescribed. As the hook 110 descends to lock the jack, one arm 116(Fig. 1) of a bell-crank lever pivoted at 118 is re leased, causing theother arm 120 of the lever to permit inward movement of side pressers122, 124 under the influence of springs 126, all as described in thefirst above-mentioned prior patent. to Fig. 10, which shows the sidepresses 122, 124 in operative position against the sides of the shoe, itwill be seen that these pressers are carried by arms 128, 130 which aremounted on rock shafts 131 and are moved toward the shoe by the springs126 and serve to measure or caliper the width of the shoe across theheel seat portion.

Before the wiper 28 begins to advance, a. tack is driven through thelower V-block or abutment 30 as described in the said firstmentionedpatent, additionally to secure the upper already firmly held clampedagainst the last at that point.

The wiper and its operating mechanism are substantially described inUnited States Letters Patent No. 1,204,928, granted November 1.4, 1916,on application of Orrell Ashton, and need not be described in detailherein. After the driving of the tack through the lower abutment 30, thecam 102 allows the gripper to clamp the upper against the Wiper in themanner described and the wiper advances over the shoe bot tom, therebytensioning the upper at the rear of the shoe, and wiping it into placeon the heel seat along the longitudinal median line of the heel, atacksupplied by a tack tube 132 being driven by a central.

driver 134 when the wiper reaches its posi tion of farthest advance overthe shoe bottom. Mounted upon each side of the central driver 134 andcarried by the wiper carrier 29 are two counter tacker frames 136, 138which are mounted for movement laterally of the shoe bottom by bolts 139which pass through holes 133 in tacker frames 136, 188 and through slots137 in brackets 141 secured t0 the wiper carrier 29 (Fig. 7).

Referring The bolts 139 are provided with spacing collars 1.45 (Fig. 8)which are longer than the thickness of the brackets 141 so that when thenuts of the bolts 139 are tightened, the bolts will still be free tomove in the slots 137. The tacker frames are held toward each other by aspring 143, as shown in Fig. 6. Tacks are supplied to these tackers bytack tubes 140, 142, and the tacks are driven'by drivers 144, 146 havinguniversal joint connection with a head 135 which also carries the driver134 and is operated by a driver lever 174 in the usual manner. On thelower side of each of the tacker frai'nes 136, 138 is a cam rol l 150.The cam rolls 150 are mounted on blocks 152 which are clamped uponflanges 155 on the lower portions 165 of the tacker frames by screws 154as is best shown in Fig. 8. The rolls 150 co-operate with cams 156, 158formed on the arms 128, 130 which carry, respectively, the side pressers122, 124. The position of the drivers and, of course, of the tackersbefore they begin to advance over the shoe bottom is indicated in Fig.9. As the tacker frames advance over the shoe bottom with the wiper, therolls 150 engage the cams 156, 158 which are so shaped as to separatethe tackers as they pass beyond the portion of the upper folded over bythe wiper and to position them at a predetermined distance from the lastedge and, of course, from the shoe engaging faces of the pressers 122,124. After the tackers have been fully separated, the direction of thecam faces on the cams 156,158 changes so as to be substantially parallelwith the movement of the wiper, and the tackers are moved forward ashort distance Without being separated further. The final position ofthe side tackers is indicated in F ig. 10 by the cross section of thedrivers 144, 146. By loosening the clamp screws 154, the rolls 150 maybe'adjusted relatively to the tack ers so as to vary the position of thetack with respect to the edge of the last, and, if desired, to locatethe tack on one side nearer to the edge of thelast than on the otherside. The tacks, however, are preferably driven mptridistant from theedge of the last and substantially midway of the inturned flange of thecorner. The tacks supplied by the tack tubes 140, 142 are delivered totack holders. each comprising two parts 160, 161 (Fig. 8) pivoted toamember 163 and held together by a spring 162, so as to separate whenthe drivers descend to drive the tack held between them. The inner facesof the members 160, 161 are recessed and by separating the parts againstthe tension of the spring 162 they may be assembled upon the projections165 extending downwardly from 1 movement of the tack holders 160, 161and of the members 163 which. are pivoted to the t acker :lrames 188 bypins 164. Each tack holder is held in elevated position by a spring 166connected between the adjacent tacker frame and a pin 169. To each oithe tack holder parts 160 is pivoted at its lower end a bar 168 by thepin 169. The bars extend upwardly along the tacker frames and have attheir upper ends laterally bent portions having holes through which passrespectively, the drivers 144;, 1 16. Above the ends of the bars 168 aresprings 170 surmounted by washers 142. When the drivers 1414, 146descend the head 135 carried by the driver lever 1741 engages thewashers 172, and compresses the springs 170 which push downwardly on tnebars 168 overcoming the tension of the springs 166 and forcing the tackholders into contact with the work. the tack holders 160, 161 when noshoe is in the machine is prevented by the flanges 155 or by the block15., clamped thereon. This dowiiward movement of the tack holdersinsures that they will come in actual contact with the work and preventsliability of the point 01 the tack shooting sideways and being driven inan inclined position as sometimes happens when tacks are insertedthrough the air, that is, from a tack holder which is slightly spacedfrom the surface of the work into which the tack is driven.

To maintain the width of: the ilioxing from the taxing seam to the heelseat constant, a gage, shown in Fig. 11, is provided. The e consists etaplate180 having in its front end a V-shaped notch adapted to receive therear portion of the shoe. The plate is dovetailed into the upper face ofthe lower V-block 30 for movement longitudinallyot the shoe, thismovement being limfited by a pin 182 engaging a slot 18% in the plate.The plate is maintained normally in "forward position by a spring 186seated in a bore in the V-block and arranged to engage the rear end 01the plate. The plate normally has a position slightly in advance of theface 01'? the V-block and the shoe, as it is swung into the machine, ispositioned with its rear end against the plate 180 and is allowed torise until its heel seat is properly positioned by engagement with thegripper 2 .3. The upper may then be adjusted downvardly or upwardlyrelatively to the last so that the lower edge of the toning will engagethe top face of the plate 180. In this Rvay the width of the toning inany given style at shoe may be maintained constant. The V-blocks l e theusual vertical adjustment by looscni the clamp nut 188 (Fig. 2) andturning the hand wheel 190 and therefore. the gage may be readilyadjusted vertically for dillerent styles of shoes, or if Excess downwardmovement ot' desired the lower V-block may be adjuster] verticallyrelatively to the upper V-lolock by loosening a clamp screw operated bya handle 189, Fig. 2.

iflechanism is provided as usual for driving a tack into the rearportion of the shoe through the upper V-block 54 preferably simulancously with the driving of the tacks into the heel seat of the shoe.The mechanism herein shown but not fully described is equivalent to thatshown in the prior patcnt first above-mentioned and will be readilyunderstood by those skilled in this art. Tacks for the upper Vblock 54are supplied by a tack tube 191.

While the operation of the various mechanisms has been given inconnection with the detailed explanation, it may be convenient br eflyto recapitulate. The shoe materials are prepared for the assemblingoperation by first securing a sole to the bottom of the last and placingover the last the upper materials comprising the lining and upperleather with a molded counter inserted be tween the lining and upper atthe rear p0- tion thereof. The upper is held to the last at the torepartby the hand of the operator and the shoe placed upon the spindle 8. Thepost 10 depressed by downward pressure of the shoe and the shoe swunginto the machine. The shoe is then allowed to rise and the upstandingmargin of the upper passes between the gripper 26, and wiper 28, the endof tie gripper engaging the inturned flange of the counter. This locatesthe last vertically and the .upper is then pulled downwardly until theseam between the foxing and quarter engages the plate 180-, thusmeasuring the width of the foxing. The shoe is then pushed against theV-block 30, and being already in contact with the gripper 26 moves thatinwardly of the machine and consequently moves the latch out ofoperative relation to the block 82 so that the treadle may be depressedto start the machine. The shoe after pushing the V- block 30 inwardlyengages the V-block 54: and moves it inwardly, causing the pawls 38 toengage the teeth 36 and arrest further movement of the lower V-block 30.

The treadle is now depressed to start the machine. The hook 110 dropsinto engagement with the roll 112 to force the jack inwardly against theV-blocks and to clamp the shoe rigidly against the lower V-lolock 30 andalso locks the post 10 against downward movement. At the same time theside clamps 122, 121 are released and are forced by their springs 126against the opposite sides of the rear portion of the shoe. The tacksupplied to the lower V-block 30 by the tack tube 192 is now driventhrough the clock into the cone of the last to assist in holding thealready clamped upper against displacement during the uppc' tensioningoperation of the gripper, this tack being preferably used in addition tothe clamping action of the post wh ch is forcing the last against thenow rigid V- block 30. The cam 102 next allows the spring 104 to forcethe gripper 26 toward the end of the wiper firmly to grip the stockwhich lies between it and the wiper. The wiper now advances, tensioningthe portion of upper between the lower V-block 30 and the gripper andwiping it over the heel. seat of the shoe. The gripper preferably gripsthe upper firmly against the wiper and is timed by. its cam 102 torelease the wiper as soon as the wiper has passed over the shoe bottomfar enough to obtain controliof the upper and insure that the tension towhich the upper has been subjected will be maintained by the pressure ofthe wiper against the heel seat. As the wiper advances the tacker frames186, 138 are carried forwardly beyond the edge of the upper at the rearof the shoe and are separated by the action of the rolls 150 against thecams 156, 158 until the tack holders 160, 161 are located over the midportion of the counter flange at each side of the heel seat andpreferably at the corners of the heel seat, whereupon a tack is driventhrough each of the tack holders which are swung downwardly against thework about their pivots 16 1 prior to the insertion of the tacks byreason of the compression of the springs 170 during the downwardmovement of the drivers. A tack is driven also through the wiper 28 andthrough the overwiped upper as is indicated in Figs. 9 and 10. At thesame time a tack may be driven if desired through the upper V-block. Thedriving of any one of the five tacks may, however, be discontinued orprevented by means shown and described in the above mentioned priorPatents No. 1,204,928 and No. 1,356,510. After the tacks are driven inthe heel seat the wiper and its attendant tacking mechanism are raisedout of contact with the work and retracted to normal position, the hook110 is raised to free the jack and restore the side clamps to normalposition, whereupon the machine stops, leaving jack free to be swungoutwardly and the shoe removed.
